T (ti/L whom, it may 007006.771:

Be it known that I, OLE O. KITTLESON, a citizen of theUnited States, residing at Lee, in the county of Lee and State of Illinois, have invented anew and useful Lubricator, of which the following isa specification.

My invention is an improved lubricator of that class wherein the lubricant is located within a cylinder and is forced gradually therefrom by means of an automaticallydriven piston, the object of my invention being to provide improved means whereby the reciprocating movement of the pistonis automatically stopped when it reaches the limit of its Working stroke and when the pressure of the piston becomes so great as to endanger the parts of the lubricator and its connections, hence avoiding breakage of the same.

My invention consists in the peculiar construction and combination of devices hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a vertical sectional view of a lubricator embodying my improvements. Fig. 2 is a top plan view of the same. Fig. 3 is a detail view taken on the line 3 3 of Fig. 2. Fig. at is a detail transverse sectional view taken on the line 4: 4 of Fig. 3.

The cylin er 1, in which the oil or other lubricant is p aced, is provided with a vertically-extending yoke 2, which rises from one side thereof and extends transversely across the upper end of the cylinder at asuitable distance above the same and is connected to the cylinder bya guide-rod 3. The piston or plunger 4, which operates in the cylinder, is provided with a removable head 5 at its upper end, and suitable packing 6 is employed between the inner side of the cylinder and the exterior of the piston or plunger,as shown.

A screw-shaft 7 extends through a threaded opening in the center of the piston-head. The said screw-shaft extends upwardly through a bushing 8, which is revoluble in an opening in the yoke 2, as shown, the said screw-shaft being provided with a flange 9, which bears against the lower side of the bushing and being secured to the bushing by a cross-pin 10. A worm gear-Wheel '11 is secured to the upper portion of the screwshaft 7 above the yoke 2.

A transversely-disposed shaft 12 is journaled and movable lengthwise in suitable bearings 13, with which the yoke 2 is provided. On the said shaft is a worm 14, which engages one side of the worm-gear 11, and loose on the said shaft is a ratchet-wheel 15, which is provided with a recess or countersink 16 on its outer side, in the face of which are radially-disposed notches 17, which are open on their outer sides. The shaft 12 is provided with projecting studs 18, which may be form ed by inserting a pin through a transverse opening in the said shaft and allowing the ends of said pin to project beyond opposite sides of the shaft, as here shown; but said studs may be formed in any other suitable rnanner. The said studs are adapted to engage the open notches 17 and lie therein, and thereby lock the ratchet-wheel to the shaft 12. It will beunderstood by reference to Figs. 2 and 3 of the drawings that the said studs, owing to the shape thereof and the shape of the sides of the. notches 17, will slip and becomedisengaged from the said notches under certain conditions hereinafter described.

the engine or machine is in operation, is

caused to constantly rock or' oscillate on the shaft 12. The said rocking lever carries at its upper end a pawl 23, which engages the upper side of the ratchet-wheel 15, and hence while the said lever is caused to rock by the means hereinbefore described the same and its pawl 23 by rotating the ratchetwheel cause the shaft 12 and worm 14 to revolve slowly and through the worm-gear and screwshaft depress the piston or plunger in the cylinder 1, and hence compress the lubricant therein and cause the same to be fed therefrom. When the piston reaches the downward limit of its stroke, and hence offers infrom the ratchet-wheel 15. Hence the continued oscillation of the lever 21 imparts no further rotatory motion to the train of gears,v

and all danger of breaking any of the parts of the lubricator or its connections is avoided. The spring (indicated at 26) is employed for the purpose of reengagi'ng the studs 17 with the notches in the ratchet-wheel at one limit of each stroke of the said lever 2l,'and thereby again start the piston in operation if the latter has been arrested in its downward movement by the pressure thereof on the lubricant before the piston reaches the lower limit of its movement.

It will be understood from the foregoing that Whenever the resistance to the descent of the piston becomesso great as toiseriously retard the rotation of the train of gears-which actuate the piston, whether this nesistancearise from the pressure of the piston onthe lubricant or by the fact that the piston has reached the lower limit of its-stroke, the studs- 17 will disengage the open notches of the ratchet-wheel, as before stated, therehy u-n-- i' clutchi ng and disconn'ecti'ngthe natchet-wheel I operatively from the osciliating lever, hence permitting the continued oscillation of the lever under the impulse of the engineer .machine, while disconnecting the actionaof the piston in the cylinder on tihelubricato-rnntizl' the resistance to the operation of the piston is removed.

A-n arm 28, which projects from the pistonhead, engages and slides on the guideerod 3 to prevent the said piston-head from rotating with the screw-shaft.

A ratchet-wheel 29 is i also loose on theshaft 12and has open notches V 30, which are adapted to be-engaged by studs 31 to lock said ratchet-wheel to the saiadzshafit.

A sprin-g-bar 32 is secured to the standard 2, as at 3334:, and has an opening near-its 11pper end, through which the shaft 12 passes.

A paw-l 35,:carried by the said spring-bar, by engagement with Lheratehet=wheel 29 pro 5 ven-ts reverse rotation of the shaft .12., 31111211 hence contributes to the rotation of the latter in the required direction by the means hereinbefore described. The spring-bar cooperates with the spring 26 to :keep th'e studs of the shaft normally in eng open notches of the ratchet-wheels.

My i mzpro ved lu bricatorisspeciailyad aipted to "feed oi-lproperlyand regularlyunder heavy steam-pressu re to the valves of a high-pressure steam-engine working at a pressure of gem'ent withthe 2 from one hundred and fifty to two hundred and fifty pounds.

By means of the nut 36, screwedon the shaft 12, the tension of the spring 26 may be regulated so as to 'predetermine the pressure in the cylinder 1, at which the downward movement of the piston 4 shall be arrested by the endwise movement of the shaft 12, here i n before described. Hence my lubricator may be so adjusted as to automatically discontinue the operation of its piston at any desired pressure before the piston reaches the bottom of the cylinder.

Having thus described my invention, I claim- 7 1. In a lubricator, the combination with a piston, ascrew-s-haftto actuate the same, a worm-'gear on said screw-shaft, an endwise- .movabl'e shaft having projecting studs, a
